The Rugby Championship kicks off for 2017 this weekend, starting with old foes New Zealand and Australia facing off in a match that doubles as the first of the three-match Bledisloe Cup series. So where will the two matches be played, what time do they kick off, and who will feature?

AOC appoint barrister to swim probe

The Australian Olympic Committee has appointed leading Sydney barrister Bret Walker SC to head its investigation into drug use and bullying by swimmers at the London Games.

The AOC on Friday said Walker would immediately begin investigating the use of Stilnox by members of the men's freestyle relay team as well as other misbehaviour.

The appointment comes a fortnight after James Magnussen, Eamon Sullivan, Matt Targett, Tommaso D'Orsogna and Cameron McEvoy admitted to using Stilnox in a team bonding exercise at a pre-Olympic camp in Manchester.

A sixth member of the relay group, James Roberts, denied taking the sleep medication but the entire group was involved in "childish and stupid" late-night misbehaviour, upsetting female teammates.

Silver-medallist Jade Neilsen claimed she and another female swimmer were subjected to "inappropriate behaviour" by some members of the men's relay squad.

Unbeaten fighter Floyd Mayweather has promised to repay any losses talk-show host Jimmy Kimmel suffers if he loses his fight against Conor McGregor.

The AOC announced it would investigate the incidents and Swimming Australia's handling of the issue after the six fronted a press conference in Canberra on February 22.

Walker, 58, has represented the AOC before in a swimming scandal when the governing body banned Nick D'Arcy from competing at the 2008 Beijing Olympics for assaulting former breaststroker Simon Cowley.

In a statement, the AOC said it "fully expects the athletes to give their total cooperation to Mr Walker's investigation".

The investigation is separate to Swimming Australia's Integrity Panel, headed by former Australian Rugby Union chairman Peter McGrath.
